Phenotypical analysis of CD38-positive B-CLL cells.

Solid lines: Freshly prepared B-CLL cells were stained with the indicated mAb by indirect immunofluorescence. Dashes: Control stainings with an irrelevant mAb. Cells were permeabilized before the staining for Bcl-2, Ki-67, and cell-cycle analysis. Data are the results of 1 representative test (patient D) of the 10 performed (A-L) on patients with CD38-positive B-CLL.
